vnEMonivrlirrfr sin ron WHEELS.

To all yuirom'z' may concern Beit known that I, Irc-1 B. BL1ss,'a citizenV 'of the United States of America, residing at Stamford, inthe county of' Fairfield, State of Connecticutfhave inventedv a new-and useful Improvement in Demountable Rimsfor IVheels, of which the following is a specification. Y

My present invention addresses itself more particularly. to heavy wheels for automobile trucks and vehicles of such nature,although it may be appliedwith approximately 'equal facility to lighter vehicles.

I have shown and described itin the present specification in 'connection with a double tire wheel, but it may be used on a single tire also; the strength and durability of'its structure however makes it more available and desirable for double tread wheels.

In a. device of this nature it is a prerequisite to so engineer the details asto provide eflicient means for preventing the slipping, or creeping, of the parts circumferentially but more especially transversely ofV the wheel structure proper, and in constructing my present arrangement I have had this endin view at all times, while of course it wasV equally desirable'to lay stress upon the removability of the necessary parts in order to provide the demountable Jfeatures which was, and is, the main purpose of my invention.

In Vorder to explain my invention more clearly I will describe it in connection with the accompanying drawings which form a part of this speciiication, and in which Figure 1- represents a side elevation of a wheel partly .in section with my invention applied.

Fig. 2 Vis a transverse section of same on the line II-II Fig. 1.

Fig. 3 is a detail view. In these drawings 10 represents the main body oi the wheel, namely the felly, made of wood or any suitable material, the spokes 11 and the hub 12.

At 13 I show my improved form of felly band;V this band is adapted to be shrunk upon the Jtelly the same as usual, my special arrangement being structural in nature and as follows I form integrally with said band and at its inner edge the posts 14 which constitute stopping, or positioning plates, for f the demountable members of the rim as will In the drawings as I have illustrated my Application and Marga "1o, '1920.' serial No. 36H05."

i plates 18 which'latter are formed invention I show awheel with a doublerubbertire 15, but my, invention canbe applied also to a wheel'with a single rubber tire; I have preferred however to show the double tire as'fr'nyY inventionis especially adapted t for'heavy truck wheels, and is engineered to meet a diiliculty heretofore unsolved.

The postsl 14 are :positioned at the inier ends lof elevated portions 16 also formed integrally .with the band 13,; see detail view,

vFig.' 3; these elevated portions constitute guides and provide locking faces, as willbe eXplained.Y Y y lThe demountable members, two in number, as engineered in the present instance i Yspeciecaton of Letters Patent. i Patented"N0V'. 16, 1920. i

are shown at 17, and are so formed as to slide laterally upon the band 13 from the outside face A' of the wheel to the inside face B, see Fig. 2, the posts 14 being placed on the inner face. Each of these members 17 holds and retains its own individual rubber tire 15 and the two units are slid on or off successively.

hen in position, as shown in Fig. 2, a i

plate 18 is placed up against the outer edge of the outer member 17 and is secured to the wheel by screw bolts 19 havingl boltheads 2O.v These bolts extend through the 'I after the manner of a flat band, as shown in ycrosssection Fig. 2 presenting its flat or vertical face to the wheel body and the felly band 13 suitable screw holes 21 in said felly band atV points coordinating with the ends of the elevated guides 16 provide means for accommodating the said bolts.

At 22 I show filling sectors Xedly secured to the demountable members 17 by rivets 23; these sectors fit in and fill the spaces on top of the band 13, and inside the demountable members 17 and between the Velevated guides 16; they constitute not only lilling plates but operate as means for preventing circumferential Vslipping of the demountable members on the telly band.

l/Vhen one of the demountable Vmembers 17 is removed the filling plates or sectors 22 come ofrn with it; they constitute when locked together a single unit.

While these filling plates, or sectors, operate as means for preventing circumferenttial-.-s'lipping, or creeping, of theV demountable members upon the felly band, the plate, 18, located as shown, constitutes in combination with the posts 14 means for preventing lateral slipping.

Y It will be seen that while the parts can be satisfactory easily secured together, or detached for repair or renewal they are firmly bound together and constitute when assembled a and powerful demountable rim orofanization. Y laving thus described my invention the following is what I claim as new and use# yful therein, and desire to secure by Letters Patent: Y

bodying a elly vband having a vseries of spaced transverse guides on itsouter face, a corresponding series ofstoppingv posts on its innered'g'e, a laterally sliding'rim member mountable Von said band and provided `with curved'sectors to occupy the spaces between the guides, an annular plate and means foi' locking said plate up against, and onto, thev outer ends ofthe transverse guides.
